Atomic 7-in-1 Set 45mm Skeleton Dial

Tsar Bomba Atomic 7-in-1 Set 45mm, reference TB8218(1+7)CF, is built as a system: a 45 mm stainless steel case with interchangeable carbon fiber bezels and seven quick-release straps. The skeleton dial exposes the movement beneath, and the case is 13.6 mm thick.

Power comes from the Miyota 82S0 automatic skeleton movement, a Japan-made caliber, under a sapphire crystal with a screw case back. Water resistance is 10 bar, or 100 meters. Every strap uses a pin buckle. The set lets the owner change the look of a single watch by swapping bezels and straps, which suits someone who enjoys customizing and wants a large, openworked automatic.
